How's that Yahoo Home page opens relatively fast and yet contains a lot of links, images? How is that done?
Consider this: - Biggest picture on their homepage is about 13Kb - They host it on hight speed and best performance servers, cause they afford to - They use content caching These amongh other "classic" reasons why a website would load fast on your computer.
That is to reduce queries against the database on high traffic database driven websites. Some template engines like Smarty have a built-in caching feature to improve performance and responsiveness of web pages. Google will give you more if take a moment to do a search on it..
If you look at the results of that report though, you'll see that there are only 4 requests and its about 5K of data with only 3 images. When I look at the page I get a whole lot more! I am guessing its sending a much smaller/cut down version to this report generator - perhaps a "mobile" version of the page. When I look at the page in firefox there is 164K of data and it takes just under 2 seconds to load....not that fast in the real world!
